Negative TV
We have a 13 inch, RCA TV in the trailer. Whenever we use it, whether on OTA or cable, the picture looks like an old negative photo. You have to stand in just the right place to see it properly. Su...

We had an old Poloroid Television (one of the very early flat screens), and it did that too. Poloroid is about the only way to really describe what's happening too. Remember the clear plastic screens you use to be able to put over your computer monitor so no one could see what was on your screen except the person sitting directly in front of it. To everyone else on the side, the screen turned black??? This is the same for the television, same principle as poloroid sun glasses. Think of the screen as a venetian blind. When the blind is open horizontal, someone standing directly in front of it can see through. When at an angle, all they can see are metal blinds.
Angle the television better. I think those older televisions were called "Plasma" screens.
Before that, all televisions used the Catho-Ray tube. A beam of light flashed 60 times a second over predefined horizontal rows across the back of the picture tub where a phosporous backing would glow. When color was introduced, the "ray" had three colors that passed those same horizontal lines, Red, Green, Blue, and a mix of those colors made ever color on the screen, cycling 60 times a second over and over across the back of the tube. Those old screens could be seen at any angle. When Plasma came out, the resolution was extremely sharp compared to the the old Catho-Ray technology, but whoever was watching, also had be directly in front of the screen. Everyone else off to the side would see a black-and-white or a color negative form of the image. Or go black completely.
